IM-chat interface design(UI 100 Days)

Hello everyone~this is my first shot of UI 100 Days——a instant message interface.
There is a little notion in this work that smartphone system can recognize the appointments among chatting, take it out smartly and show a disinteruptted alert to convenient users' operation.
Also I add some 3D rotating type of transformation in cards style, make it more unique.
I resolve to insist uploading my mobile design works from now, but maybe can't update daily for busyworking.If u want to join me, please follow me @Monini .Thanks for your support:)
